A 20-minute ceremony was held prior to playing the Washington Capitals, the previous Cup champions.
"It's a great moment," Blues captain Alex Pietrangelo said. "I think we'll have a couple days here to kind of reflect on it, but it was good. It was obviously tough when you're trying to flip the switch and get ready for the game, but obviously a pretty special moment."
The Stanley Cup sat on a table in the Zamboni entrance while the Blues walked past it on the way to the ice during player introductions. Ryan O'Reilly, the next-to-last player introduced, carried the Conn Smythe Trophy, which he won voted as most valuable player of the playoffs. He was followed by Pietrangello, who picked up the Cup from the table and carried it onto the ice to begin a procession around the rink.
